The rotation of the member 9 in the opposite direction will reverse the operation of the jaws.

sioning will permit such gripping. wire 24 is not. gripped between jaws and it is desirableto remove the wire 24, then it may Projecting from the inner'face of each jaw is a lug 23 which acts as a support for the feeder wire 24. The jaws will open far enough so that the inner edges of the members 23 will be spaced far enough apart, to permit the passage'of the wire'2t therebetween. The wire 24: is not necessarily gripped bythe jaws although proper dIimepf t 1e be merely'drawn out of the awslongitudinally without disturbing the trolley wire 17.

It will be noted that the trolley wire and the feeder wire are held in a common vertical plane which coincides with the vertical axis of the device. Therefore, there is no tendency for a'bending strain upon the device due to the position of the wires 17 and 24, and likewise the width of thedevice is 7 made a minimum which is essential due to the fact that the groove current collector moves along the trolley wire 17 and as little interference should be produced with the current collector as possible, and, therefore, it it necessary to maintain the width of the device as small as possible.

Toinstall the device upon a support, the device is first secured thereto by the threads upon the member 1 and" the jaws 16 are brought into proper alignment with the trolley wire 17. The member 9 is then rotated to move with the jaws to their open position and enough to permit the wire 24 to be placed therebetween, and the member 9 is then rotated in the opposite direction to close the jaws sufficiently to prevent the wire 24 from dropping away from the jaws but rest upon the lugs 23 as shown in Fig. 4. This operation be carried out with a succession of the. clamps thereby positioning the wire 24. Having done this, the trolleywire is then placed in position and preferably drawn. taut and then it is raised up slightly to insert bev tweenthe lips 16 and the jaws and the member -a succession of the devices and then the. member 19 can be'drawn up. tightly by means of a wrench. Of course, there are modifications to this method of installing the device which may becarried out, as will be obvious.

While the wire 24 may be tightly clipped i as before stated, I find that there is an ads vantage in having it rest loosely between the jaws as already pointed out and I. do not find that this is a detriment to the wire 24 acting as a feeder for the trolley 17 and the trolley 17 is not necessarily made dependent for its current upon'the wire 24 as usually the trolley 17 is connectedfto the sources of means to secure the jaws to a hanger, means to move the jaws into or out of engagement with the conductor at will, means along one edge of the jaws to engage the conductor and inwardly projecting means upon the aws to support an auxiliary conductor at a distance from and parallel with the first said conductor.
